Your only major options currently are to farm for chips/items or level up.Or help spade stuff or whatever. There is, like I mentioned before, a 'quest' later, but essentially, it's just a variety of leveling up.

The RNG stands for Random Number Generator. A general term used to describe, well, the random number generator.I don't know how it's coded here, but suppose the computer has a 25% chance of showing up each turn.It is possible to go an almost infinite number of turns without encountering it, as the chance of it showing up is not 100%, though the probability of that happening is very low.So what I meant is that there are times that it will take a long time for a certain thing to show up, and there are times that it may show up very frequently.I had assumed you knew the term, as it's very common in these kinds of games.

No, that was another term I take for granted.Spading is figuring stuff about the game. Monster difficulty, xp gains, damage you do with certain powered weapons, etc. Then you can contribute what you find to the wiki, the link to which is somewhere in the main discussion forum.
